Spillway Hydraulic Issues in Rebuilding Embankment Dams-Ezperiences from Vattenfalls Dam-Safety Program
In the light of the revised design floods and higher dam-safety requirements,many dams,owned by Vattenfall,have been rebuilt and many others undergo dam-safety evaluations or an upgrading process.Depending upon the dam in question,hydraulic concerns arising from the dam rebuilding may cover dam-slope erosion close to the spillway,increase of spillway discharge capacity,construction of new spillway or rebuilding of existing spillway,reshaping spillway channel,enlargement of stilling basin or plunge pool and risk for erosion in the dam toe or in the river channels downstream.In this paper,experiences and hydraulic issues of attention are summarised and discussed in the rebuilding of a number of embankment dams.
